There are three main types of rebreathers. They are closed circuit, open, and mixture. Each has its own advantages and drawbacks. This article will discuss the most popular rebreather types and what you should look out for when selecting a rebreather. The last section will detail which rebreathers can't disrupt marine life. It doesn't matter what rebreather you choose; make sure it works in the environment you are going to be.
Semi-closed circuit Rebreathers
You might choose to compare semi-closed circuit and closed-circuit rebreathers systems when you have the option. However, these two types of rebreathers are largely similar in principle, and the primary differences are in the way gas is delivered and mixed. Whether you choose a closed-circuit rebreather or a semi-closed circuit model depends largely on your specific requirements and goals.
Continuous-flow "mixture rebreathers"
Although most continuous-flow breathing devices are not designed for long diving, the newer versions can allow you the same oxygen level as your environment. This allows you to breathe easier and protects against bacteria contamination. The rebreathers are also more durable and reliable than ever before. As long as the rebreathers are used properly, they won't be able to inhale water.
Purging oxygen rebreathers
To provide constant gas flow, a rebreather diver must have access to oxygen. The source of gas is stored in a cylinder that is attached to the diver's rebreather. Liquid oxygen (or pure oxygen) increases the effort of breathing. The rebreather diver must breathe in a mixture of both gases. There are two types rebreathers. Both types of rebreathers are similar. The difference between the rebreathers lies in their volume of gas. Divers should know both, as it is the best method to prevent hypoxia.
Rebreathers don't disturb marine life
Rebreathers are quiet and don't disrupt marine life. Rebreathers offer underwater diving a quieter experience than open-circuit divers, which are noisy with gushy and clogged gas. Rebreathers are also much more comfortable than other diving equipment, so the only concern you should have is how comfortable you'll be breathing.
Rebreathers are expensive
Rebreathers are vital medical equipment for personnel in law enforcement and military. Rebreathers are becoming more popular due to the safety benefits and cost savings. The high cost of these devices might discourage many from using them. Below are some ways to reduce the cost for rebreathers. Continue reading to find out more.
Safety concerns of divers using rebreathers
Rebreather safety problems are rare but do exist. Rebreather diving is up to 10 times more risky than open-circuit scuba, according to some studies. Rebreather diving actually causes fewer deaths than base jumping or skydiving. To minimize risk, rebreather users need to be committed and persistent in following the safety protocols.
